With roughly 11 million unauthorized immigrants living in the United States, some question whether the nation’s immigration laws are being seriously enforced. In truth, due to legal and policy changes in recent years, the immigration laws are enforced more strictly now than ever before. The Department of Homeland Security (DHS) has reported record numbers of removals during the Obama administration, especially of noncitizens with criminal convictions. Meanwhile, fewer noncitizens are trying to enter the country illegally, and those caught by the Border Patrol are now regularly charged with federal crimes. Together, these trends reflect a sweeping and punitive transformation in U.S. immigration enforcement.

When noncitizens who violate the immigration laws are forced to leave the United States, their departure is classified as a “removal” or a “return.” (See the glossary for definitions of these terms.) DHS reported 391,953 “removals” during the 2011 fiscal year, slightly below the record set in 2009. Meanwhile, DHS reported 323,542 “returns” in 2011, the lowest number since 1970 {Figure 1}.
